BUFFING AND POLISHING WHEEL.

7 '0 all whom it may concern.

Be it known that 1, HENRY L. ZUCKER, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Buiiin and Polishing Wheels, of which the f0 lowing is a specification.

My invention relates to improvements inbufiing and polishing wheels. I

One object of the invention is to provide a bufiing or polishing wheel which is substan-' tially ready for use in the form in which it is sold.

Another object is to provide a wheel of this character, the periphery of which is impre' mated or treated with a material which facilitates the application of the final abrasive coating by the Workman, and avoids waste of material.

In carrying out my invention, after balancing a bufling wheel of predetermined size by arranging the individual sections in proper relation to each other, and marking' them to insure proper reassembly, I true up the surface by a specially constructed tool, rotating the buffing wheel in a specially constructed machine which is arranged to draw off most of the lint. The bufling wheel is then thoroughly impregnated with a material which completely fills the interstices of the fibers and so prepares the periphery as to enable it to take the final polishing material immediately and without waste. The material used is a grease having a high melting point. This impregnation is accomplished preferably by applying the material in liquid form by means of a comb or tool having a number of fine points, over which the liquid flows into and between the various layers of cloth, which make up the bufiing wheel. The periphery of the wheel is composed chiefiy of projecting fibers or a nap, which by capillary attraction readily absorb and hold the impregnating compound. The chief function of the liquid is to so prepare the fibers that they shall require only a' comparatively light coating of abrasive when used by the workman, although said liquid impregnating material may .also have the properties of an abrasive in various degrees. The abrasive is preferably a composition made up of decomposed silica, pulverized flint, stearic acid, mutton tallow and pet- Speoifloatlon of letters latent.

rolatum. The initial application of the grease causes the fibers to become impregnated as a result of which, when the workman applies the final abrasive, the said abrasive is held to the fibers instead of being thrown off into the exhaust.-

In what are known as pieced bufl's, it is practically impossible to obtain a perfect balance in the individual sections. In buffs made of full disks of cloth, it is possible to obtain a perfect balance in the individual A tate it, apply the usual coating of polishing sections. The completed bufl' may be sold in the form in which it is finished and used material, which has to be applied from time to time in the daily operation in any case, and press the work piece against the periphery.

The bufiing and polishing wheel shown in the accompanying drawings will serve to illustrate the improvement described herein.

Fi ure 1 is a front elevation of a biifling whee made up of individual sections.

Fig. 2 is a side elevation thereof, and

Fig. 3 is a front elevation of an individual section.

The bufling or'polishing wheel 1 or buff, asit is called, consists of a plurality of individual thin bufiin wheels 2 or buffing wheelsections. Eac section consists of a plurality of layers of cloth which may be complete flat disks or other conventional arrangement of the fabric. The individual cloth layers are preferably stitched together as shown at 3 in Fig. 2. The composite buff 1 is built up of any desired number of such individual sections, which are mounted on an arbor (not shown) and clamped-together is absorbed by this nap and the fabric immediately beneath it forming an impregnated outer ring 5.

Since the invention may be embodied in various forms, I do not desire to limit myself to the particular type of buflin r wheel disclosed herein except where limitations appear in the appended claims.

I claim:

1. As a new article of manufacture, a buffing wheel section comprising pieces of cloth stitched together and of clrcular outline, the outer periphery only being impregquire merel nated with a substance which facilitates the adhesion of an abrasive.

2. As a new article of manufacture, a buffing wheel comprising la ers of fabric held together, having a circu ar outline and with the peri heral threads forming a nap, the nap only bein r so impregnated as to rea nal e abrasive coating to render said ufling Wheel effective.

In testimony whereof I have subscribed my name.

HENRY L. ZUCKER.
